Garmin GI 275 offered by SEA as Part 25 IVSI replacement


Southeast Aerospace (SEA) has received FAA STC number ST02004WI for the installation of the Garmin GI 275 3.125in round display electronic flight instrument in Part 25 aircraft on an approved model list as an instantaneous vertical speed indicator (IVSI).

SEA joined with Garmin and Peregrine to develop a solution to replace IVA-81A and IVA-81D IVSI units in Part 25 aircraft by utilising the IVSI version of Garmin’s GI 275 electronic flight instrument.

The STC allows the Garmin dealer to install the GI 275 IVSI on any aircraft on the AML. The STC approves removing and replacing a single or dual IVA-81A/D IVSI units. The customer can install two new GI 275 units or retain a single IVA-81A/D and replace the other existing IVA-81A/D with the GI 275. The GI 275 IVSI STC covers three interface scenarios for the required air data input to drive the IVSI needle.

“We’re thrilled to work with Southeast Aerospace on this STC, which will provide the GI 275 IVSI replacement for a variety of Part 25 aircraft,” said Carl Wolf, Garmin vice president, aviation sales and marketing. “The GI 275 upgrade will offer operators a modern and cost-effective replacement solution to avoid the high repair costs and ongoing obsolescence associated with legacy IVSI on these aircraft.”

Specific TCAS II systems supported by this STC include the Bendix King CAS 6X(X), CAS 100(X) and Garmin GTS 8000. The GI 275 is intentionally designed to take advantage of the common 3.125in flight instrument size, reducing installation time and preserving the existing aircraft panel.

SEA has designed a 3-ATI to 3in adapter plate to allow for an easy upgrade to the GI 275 IVSI into the standard 3-ATI cutout. The adapter plate will be available for purchase with the STC. SEA is also supplying an adapter wiring harness that will plug into the existing IVA-81A/D connector with no additional wiring required in most cases.

“We are excited to be able to provide a quick-turn and a non-invasive upgrade option for ageing legacy equipment while also offering a product that has a long life ahead with possible features expansion in the future,” said Luke Gomoll, SEA aircraft modifications sales representative.

“Our relationship with Southeast Aerospace continues to bring additional avionics capability to meet market demand,” said TJ Spitzmiller, VP of business development with Peregrine. “The versatility of Garmin’s products such as the GI 275 is yet another exciting addition to their line-up.”

Southeast Aerospace’s Part 25 AML IVSI STC is available for business aircraft including Learjets, Citations, Hawkers, Gulfstreams, Challengers, Falcons and more.
